This invention relates to hydraulic irrigating apparatus for use inirrigating the intestinal canals.

An object of the invention is to provide such a device with a pulsatingdelivery which will have a massaging effect upon the walls of theintestines'and which, by intermittently expanding the intestines, willbreak loose anyconcretions that may be adhering thereto. This hydraulicvibratory massage has a stimulating and beneficial influence on theintestinal tissues and breaks up and washes away adhering toxic matterthat could not otherwise be removed. v

A further object is the provision of means for varying the force andfrequency of the pulsations to adapt the treatment to the condition andneeds of the patient. a

The apparatus is particularly useful for administering high enemas,since the alternating stretching and relaxing of the bowel walls assistin inserting the head of the irrigator' into the upper intestine. V 4

While preferred forms of the invention have been disclosed for purposesof illustration, it should be understood that changes may be made in thestructure without departing from the spirit and scope of the 1nventionas hereinafter set forth and claimed.

In the drawings: Fig. 1 is an elevation of one embodiment of theinvention.

Fig. 2 is a section through the interrupter valve of Fig. 1.

Fig. 3 is an enlarged elevation of the nozzle used in Fig. 1.

Fig. 4 is an elevation partly in section of a modified form of theinvention. 7

Fig. is a view similar to Fig. 4- showing a further modification.

Referring to the drawings more specifically, reference numeral 10indicates a water reservoir of any suitable material, such as glass, andsituated at about six or eight feet above the floor to produce a properpressure at the nozzle. Numeral 11 refers to the double nozzle, which isshown on an enlarged scale in Fig. 3. This nozzle comprises an outertube 12 having one end tapered and closed as at 13. while the oppositeend is open.

as at 14. A delivery tube 15 passes through the side of the tube 12above its open end,

extends along the axis of tube 12, and is oined: to the inner wallof'tapered end .13

att16. The end 13 is pierced with apertures ing thereacross, andconnected to the drive motor 23..

When this irrigatoris in use the motor revolves the interrupter valve,thereby periodically interrupting flow through feed-line 19 and causingpulsating discharge from the dehvery nozzle. The speed ofthe motor canbesuitably controlled to govern the du ration of the pulsations.

In the species shown in Fig. 4 the force of the discharge-is derivedfrom a power pump instea'diof from gravity feed. This species isillustrated ashaving a single nozzle 24, although obviously it may'havea double nozzle as in Fig. 1 if desired. The feed line ex-- tendsfromthe-nozzl'e to the reservoir 26, and

the forcepump 27 is interposed in the feed line. The pump 27 is a singleacting plunger pump with check valves 28 arranged so that the pump drawsliquid from the reservoir and forces it toward the nozzle. The. crankarm 29of. the pump is operated'by a gear wheel 30 which carries aplurality of crank pin holes 31 distributed along: its radius to providemeans for varying the length of the stroke of the pump. Wheel 30 ismoved by. a motor 32 through worm. 3.3,. and the.- variable resistance34 provides meansfor varying both the frequency and intensity of thepulsations delivered by the nozzle. 7

In the species of Fig. 5 the pump 35 is driven by a motor 36 throughreduction ears 37 and 38. The valve arrangement is similar to that ofFig. 4 but a by-pass 39 leads from the delivery chamber 41. A screwvalve 42 controls the amount of liquid delivered through the by-pass.This apparatus is provided with a double nozzle similar to that shown inFig. 1. In this device the screw 42 may be adjusted While the pulsatoris Working to regulate the pressure and volume of Water delivered by thenozzle.

I claim:

1. An intestinal irrigator comprising a nozzle adapted for insertioninto the intestines, a source of liquid supply, a feed line connectingthe nozzle to the source of supply, a reciprocating pump in said feedline to cause a pulsating delivery from the nozzle, and means forregulating the stroke of the pump to vary the amount of Water deliveredat each pulsation.

2. An intestinal irrigator comprising a nozzle adapted for insertioninto the intestines, a source of liquid supply, a feed line connectingthe nozzle to the source of supply, a reciprocating pump in said feedline to cause a pulsating delivery from the nozzle, and means forregulating the speed of the pump to vary the rate of pulsation.

3. An intestinal irrigator comprising a nozzle adapted for insertioninto the intestines, a source of liquid supply, a feed line connectingthe nozzle to the source of supply, a reciprocating pump in said feedline to cause a pulsating delivery from the nozzle, said pump beingprovided with a bypass connecting its delivery chamber to its inlet, andadjustable means to regulate the amount of flow through the by-pass tothereby vary the volume of liquid and the force of each pulsation.

4. An intestinal irrigator comprising a nozzle adapted for insertioninto the intestines, a source of liquid supply, a feed line connectingthe nozzle to the source of supply, a reciprocating pump in said feedline to cause a pulsating delivery from the nozzle, means for drivingthe pump at a uniform speed, a by-pass forrelieving part of the pressurein the delivery chamber of the pump, and means operable While the pumpis Working to regulate the flovv through the by-pass to thereby vary thevolume of liquid and the force of each pulsation.

5. An intestinal irrigator comprising a nozzle, adapted for insertioninto the intestines, a source of liquid supply, a feed line connect--ing the nozzle to the source of supply, and a motor driven reciprocatingpump in said feed line, said pump being adapted to cause a pulsatingdelivery from the discharge nozzle.

In testimony whereof I altix my signature.
